OUTFIL Repeating Example

Scenario -

Create three output files like below -

Repeat dept1 records 1 time, move to file1 and add 1 digit sequence number from 60th byte starting from 1 and increment by 1.
Repeat dept2 records 2 times, move to file2 and add 2 digit sequence number from 60th byte starting from 2 and increment by 2.
Repeat dept3 records 3 times, move to file3 file2 and add 3 digit sequence number from 60th byte starting from 2 and increment by 3.

Explaining Example -

SORT FIELDS=(1,5,ZD,A) - sort all outputs in ascending order based on the ZD value from 1 to 5 positions.
OUTFIL FNAMES=OUTPUT1,INCLUDE=(30,5,CH,EQ,C'dept1') - All the records marching with "dept1" from the 30th position of length 5 will be copied to output1 file.
OUTFIL FNAMES=OUTPUT1,.., BUILD=(1,59,...) - Copies 1 to 59 bytes data from input file to output file1 as it is (which satisfies the above condition).
OUTFIL FNAMES=OUTPUT1,.., BUILD=(1,59,X,..) - Add space to the 60th byte.
OUTFIL FNAMES=OUTPUT1,.., BUILD=(..,SEQNUM,1,ZD,START=1,INCR=1) - generates the sequence number in OUTPUT1 file starts with 1 and increments by 1 every time from 61st byte of length one byte.
OUTFIL FNAMES=OUTPUT2,INCLUDE=(30,5,CH,EQ,C'dept2') - All the records marching with "dept2" from the 30th position of length 5 will be copied to output2 file.
OUTFIL FNAMES=OUTPUT2,.., BUILD=(1,59,...) - Copies 1 to 59 bytes data from input file to output2 file as it is (which satisfies the above condition).
OUTFIL FNAMES=OUTPUT2,.., BUILD=(1,59,X,..) - Add space to the 60th byte.
OUTFIL FNAMES=OUTPUT2,.., BUILD=(..,SEQNUM,2,ZD,START=1,INCR=2) - generates the sequence number in OUTPUT2 file starts with 1 and increments by 2 every time from 61st byte of length 2 bytes.
OUTFIL FNAMES=OUTPUT3,INCLUDE=(30,5,CH,EQ,C'dept3') - All the records marching with "dept3" from the 30th position of length 5 will be copied to output3 file.
OUTFIL FNAMES=OUTPUT3,.., BUILD=(1,59,...) - Copies 1 to 59 bytes data from input file to output3 file as it is (which satisfies the above condition).
OUTFIL FNAMES=OUTPUT3,.., BUILD=(1,59,X,..) - Add space to the 60th byte.
OUTFIL FNAMES=OUTPUT3,.., BUILD=(..,SEQNUM,3,ZD,START=1,INCR=3) - generates the sequence number in OUTPUT2 file starts with 1 and increments by 3 every time from 61st byte of length 3 bytes.
